Kai's verdictS-tier for builders. The right primitives. What Kai is built on under the hood.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Still early. Manus is more flexible for less money.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
